This is something to try: Try removing line 103.
What your mapping says is: All of the AbstractCommand fields (in any
order) and then the Data, Correlator fields (in any order). But the
AbstractCommand fields are a single structure, and must be grouped
together.
The <mapping extended=""> automatically includes the fields from the
extended class, there isn't any reason to repeat structure in the Alert
mapping.
